Search for high energy γ-rays emission in28Si,32S+64Ni dissipative reactions at about 5 MeV/amu incident energy

Photons emitted in the28Si+64Ni and32S+64Ni reactions at 143 MeV and 156 MeV incident energy respectively, have been detected in coincidence with the ejected charged fragments. An array of 48 BaF2γ-rays detector and 6 solid state silicon detector telescopes have been used. Photon energy spectra measured in the energy range from 2 to 20 MeV in coincidence with ejectiles coming from deep inelastic reactions, are consistent with statistical emission from the reaction products.
